Definitions

  • This invention relates to a multilayer structural building material suitable for use as a backing material in walls, ceilings, floors, etc.
  • Backing materials composed of polyolefin or polybutadiene foams have heretofore been used to produce a heat insulating effect and a cushioning effect between a base material such as a wall, ceiling, floor, etc. and a surface material such as a wall paper and a nonwoven fabric. Since, however, the polyolefin or polybutadiene foams generally have low polarity or a low surface tension, only a limited number of adhesives are available which have high adhesiveness and can withstand use. In general, organic solvent-base adhesives obtained by dissolving natural and synthetic rubbers, acrylic copolymers, etc. in organic solvents are frequently used.
  • the surface material is available in many design patterns, end in order to match design patterns, it is inconvenient to bond the surface material to a backing material in advance.
  • an organic solvent-base adhesive is coated on the surface of a base material such as a wall and the surface of a backing material, and after drying, the coated surfaces are bonded to each other.
  • the bonded material has high adhesion, but after the bonding operation, it is extremely difficult to make a subtle change in the position of the backing material or remove creases.
  • the bonding of a surface material to the backing material is performed in the same way.
  • the present invention provides a multilayer structural building material comprising a polyolefin or polybutadiene foam sheet as a base layer, a dry coated layer of a polychloroprene-type adhesive as an interlayer, and a dry coated layer of a mixture of a water-base adhesive and an inorganic filler as a surface layer.
  • the multilayer structural building material of the invention is most suitable for use as a backing material in walls, ceilings, floors, etc.
  • Polyolefinic resins used as a starting material for the foam sheet in accordance with this invention include homopolymers of olefins such as ethylene, propylene, butylene and isobutylene, copolymers of at least 50% by weight of the above-exemplified olefins and comonomers such as vinyl acetate, methyl acrylate, ethyl acrylate, butyl acrylate, methyl methacrylate, acrylic acid and styrene, and copolymers of at least 50% by weight of at least two of the above-exemplified olefins.
  • olefins such as ethylene, propylene, butylene and isobutylene
  • copolymers of at least 50% by weight of the above-exemplified olefins and comonomers such as vinyl acetate, methyl acrylate, ethyl acrylate, butyl acrylate, methyl methacrylate,
  • polystyrene resins examples include polyethylene, polypropylene, an ethylene/vinyl acetate copolymer, an ethylene/propylene copolymer, an ethylene/butyl acrylate copolymer, and a sodium salt of an ethylene/ acrylic acid copolymer.
  • polyethylene, an ethylene/vinyl acetate copolymer and polypropylene are preferred, and polyethylene is especially preferred.
  • the polybutadiene used as a starting material for the foam sheet in accordance with this invention denotes not only polybutadiene, but also copolymers containing at least 50% by weight of a butadiene unit.
  • examples of comonomers which can be used to prepare such butadiene copolymers include styrene, acrylonitrile, chloroprene, and methyl methacrylate.
  • polybutadiene resins polybutadiene and a styrene/ butadiene copolymer are preferred.
  • a polymer blend containing the aforesaid polyolefinic resin and polybutadiene resin as a base can also be used to produce the foam sheet in accordance with this invention.
  • the polyolefinic resin is preferred to the polybutadiene resin, and polyethylene is especially preferred.
  • the foam sheet may be provided in various thicknesses and apparent densities depending upon the material which constitutes the sheet and upon its uses.
  • Suitable foam sheets 1 have a thickness of 2 to 30 mm, and an apparent density of 0.02 to 0.05 g/cm 3 . If the sheet 1 has an open cellular structure, it is difficult to coat,an adhesive (to be described hereinbelow) on it, and its water permeating property adversely affects the base material. Closed cellular foam sheets, on the other hand, are suitable for use in architectural backing materials because of their excellent thermal insulation, compression characteristics, water resistance and non- permeability to water. Accordingly, the latter type gains much acceptance.
  • the dry coating 2 of a chloroprene-type adhesive and the dry coating 3 of a mixture of a water-base adhesive and an inorganic filler are coated on one surface of the sheet 1 as shown in Figure 1, and preferably on both surfaces of the sheet 1 as shown in Figure 2.
  • the chloroprene-type adhesive used in the invention is a solution of a chloroprene rubber in a suitable organic solvent such as toluene, hexane, ethyl acetate and mixtures thereof.
  • a suitable organic solvent such as toluene, hexane, ethyl acetate and mixtures thereof.
  • the chloroprene rubber preferably has a degree of crystallization below a medium level and a crystallization speed below a medium level. If desired, a tackiness-imparting agent, a curing agent, etc. may be added to the chloroprene-type adhesive.
  • chloroprene rubber examples include copolymers, blocked copolymers and graft copolymers of chloroprene and comonomers such as vinyl acetate, methyl acrylate, methyl methacrylate, acrylic acid, vinyl ether and glycidyl methacrylate.
  • a graft copolymer of chloroprene with vinyl acetate or methyl acrylate is preferred.
  • the chloroprene-type adhesive used in this invention generally has a solids concentration of 5 to 30%, and the amount of its coating is suitably 1 to 30 g/m2 calculated as solids.
  • tackiness imparting agent examples include phenolic resins, petroleum resins and natural resins, and examples of the curing agent as an optional component include toluene diisocyanate, and metal oxides such as magnesium oxide and zinc oxide.
  • a mixture of a water-base adhesive and an inorganic filler is coated thereon to form a dry coated layer 3 of the mixture.
  • water-base adhesive denotes an adhesive which is used as a solution or dispersion in water, and develops adhesion strength upon removal of water.
  • water-dissolved adhesives are polyvinyl alcohol, methylol urea, methylol phenol, gum arabic and starch pastes. Polyvinyl alcohol is preferred.
  • water-dispersed adhesives are vinyl acetate-type adhesives, acrylic adhesives and vinyl ether-type adhesives, and the vinyl acetate-type adhesives are preferred.
  • the water-dispersed adhesives are preferred to the water-dissolved adhesives, and the vinyl acetate adhesives are especially preferred.
  • the vinyl acetate-type adhesives also include aqueous dispersions of copolymers of at least 50% by weight of vinyl acetate with a comonomer such as acrylic acid, ethylene, and an acrylic acid ester such as methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, 2-ethylhexyl acrylate and hydroxyetbyl acrylate.
  • a comonomer such as acrylic acid, ethylene, and an acrylic acid ester
  • methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, 2-ethylhexyl acrylate and hydroxyetbyl acrylate such as methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, 2-ethylhexyl acrylate and hydroxyetbyl acrylate.
  • a mixture of two or more water-base adhesives may also be used.
  • the "inorganic filler”, as used herein, denotes a fine powder of an inorganic material.
  • examples of such an inorganic material include calcium carbonate, calcium sulfate, aluminum oxide, magnesium oxide, calcium silicate, aluminum silicate, silicic anhydride, aluminum hydroxide, talc and clay.
  • Inorganic fillers which have been calcined or treated with coupling agents, etc. are also included within the inorganic fillers used in this invention.
  • the aluminum compounds are preferred, and a fine powder of aluminum hydroxide and a fine powder of aluminum silicate are especially preferred, and give good results in regard to overall properties including fire retardancy, operability in bonding, and retention of adhesion strength.
  • the inorganic filler used in the architectural backing in this invention is preferably bulky, and is used in an average particle diameter of preferably 0.1 to 300 microns, especially preferably 1 to 100 microns, and most preferably 10 to 50 microns. If the average diameter of the inorganic filler is less than 0.1 micron, many cracks occur in the inorganic filler-containing layer of the building material at the time of bending, and if it exceeds 300 microns, the storage stability of the mixture of the water-base adhesive and the inorganic filler is poor, and the solids (the filter and the-solid component of the adhesive) separate and settle down.
  • the proportion of the inorganic filler is 50 to 90% by weight, preferably 70 to 80% by weight, based on the total weight of the inorganic filler and the solids of the water-base adhesive. If it is less than 50% by weight, the backing materials obtained adhere to each other under the influence of water, humidity, heat, mechanical pressures, etc., and it is sometimes necessary to insert sheets of releasing paper between the backing materials. This not only greatly reduces the efficiency of working at the site of construction, but also increases the cost. Moreover, the multilayer structural building material become relatively stiff, and numerous cracks occur on its surface. On the other hand, if the proportion of the inorganic filler exceeds 90% by weight, the . inorganic filler scatters from the surface of the multilayer structural material upon friction, etc., and its adhesiveness becomes unstable.
  • a mold-proofing agent a fire retardant, a viscosity controlling agent, etc. may be incorporated in the mixture of the water-base adhesive and the inorganic filler.
  • the amount of the mixture of the aqueous water-base adhesive and the inorganic filler to be coated is 2 to 50 g/m 2 , preferably 5 to 20 g/m 2 , calculated as solids, and the amounts within'this range give good results.
  • the mixture of the water-base adhesive and the inorganic filler may be coated on the entire surface of the sheet 1, or in dots, lines, curves, etc. Desirably, the coating is carried out by a gravure coating technique.
  • the amount of the mixture of the water-base adhesive and the inorganic filler exceeds 50 g/m 2 , cracks occur in the resulting product at the time of bening. If it is less than 2 g/m2, blocking occurs, and the adhesiveness of the resulting product which is attributed to the use of the water-base adhesive becomes unstable.
  • the dry coated layer of the mixture of the water-base adhesive and the inorganic filler does not adhere to itself even when water is included therein, pressures are applied thereto, or it is dried. Nor does it adhere to other materials upon application of heat to its surface.
  • the structural material of this invention is to be bonded to a wall paper by a water-base adhesive using a laminator in a factory, the trouble of adhering of the structural material to a hot roll is. obviated in the drying step, etc.
  • the structural material of this invention is flexible, and even when bent, does not develop cracks and creases on its surface.
  • the dry coated layer 3 of the mixture well absorbs a starch-type adhesive, a vinyl acetate emulsion adhesive, etc. to contribute to firm adhesion.
  • a water-base adhesive such as a vinyl acetate-type adhesive is coated on a wall or the structural material of this invention, and then the structural material is press-bonded to the wall.
  • a water-base adhesive such as a starch-type adhesive or a mixture of it with a vinyl acetate-type adhesive, is coated on the structural material of the invention or on a wall paper, and then the wall paper is lightly press-bonded to the structural material of this invention. Then, within a short period of time, 1he position of the wall paper is adjusted, creases are removed, the air entrained is removed, etc. to complete the bonding operation.
  • the structural material of the inventian as shown in Figure 1 is useful as an intermediate material in bonding a wall paper thereto by means of an organic solvent-base adhesive in a factory which maintains a good environmental control, and a heat-insulating wall paper which can be applied by means of water-base adhesives is obtained.
  • the structural material of this invention can be bonded to a floor material such as concrete, and a surface material composed of asbestos slate, a hardboard, a plywood, etc. can be bonded to the structural material.
  • a surface material composed of asbestos slate, a hardboard, a plywood, etc. can be bonded to the structural material.
  • the surface material is a parquet tile
  • such tiles are frequently joined by so-called rabbet joint utilizing tongues and grooves provided on the side surfaces of these tiles.
  • the surface material (parque tile) is required to be movable relatively easily while it is in contact with the backing material. Since the structural material of this invention is applied by means of a water-base adhesive, meticulous adjustment of joining is very easy until the bonding strength of the surface material develop.
  • the multilayer structural building material of this invention having the above-described construction is easy to handle and has good storage stability. Furthermore, before the water-base adhesive used to bond the multilayer structural building material of this invention to the surface material dries, the exchange of the surface material and the change of its position can be effected easily. Furthermore, removal of creases or entrained air can be easily effected when the surface material is a wall paper or the like. After the water-base adhesive has dried, excellent adhesion strengths at the bonded surface can be obtained.
  • the multilayer structural building material of this invention is also advantageous in controlling works and materials.

  • a dry coated layer of a polychloroprene-type adhesive (2 g/m 2 ) and a dry coated layer (10 g/m 2 ) of a mixture consisting of 75% by weight of aluminum silicate and 25% by weight of a copolymer of 90% by weight of vinyl acetate and 10% by weight of ethylene were formed in the same way as in Example 1 on both surfaces of a crosslinked polyethylene foam sheet having an apparent density of 0.025 g/cm 3 and a thickness of 4 mm.
  • the resulting product had an appearance and properties which well withstood practical use. Its adhesive properties with respect to a veneer, a slate and wall papers were as shown in the following table. The adhesive properties were measured as follows:
  • the materials shown in the above table were bonded by using each of the specified adhesives, fully dried, and then subjected to a 180 peel test by hand at room temperature.
  • the surface coated with the adhesive was as follows:
  • a measuring sample (with 20 mm, length 70 mm) as shown in Figure 3 was prepared, and subjected to a 180° peel test under a fixed load in water.
  • the reference numeral 4 in Figure 3 shows the veneer or slate and the reference numeral 5 shows the product of the invention.
  • the reference numeral 4 shows the product of this invention and 5, the wall paper.
  • the reference numeral 6 represents a load, and 7, a bonded surface.
  • a primer composed of a 10% by weight toluene solution of low-crystalline chloroprene rubber as a main ingredient at a rate of 15 g/m 2 (as a solution), and fully dried.
  • a mixed solution consisting of 100 parts by weight of an aqueous solution of polyvinyl alcohol having a solids content of 15% by weight, 100 parts of calcined aluminum silicate having an average particle diameter of 40 microns and 140 parts by weight of water at a rate of 10 g/m 2 (as solids), followed by drying with hot air at 80°C.
  • the resulting multilayer structural building material was a pliable white sheet having a tack-free surface, and did not undergo cracking at the surface even when bent.
  • a commercially available starch paste was coated on a veneer, a concrete plate, a gypsum board and a wall paper, respectively, and the treated surface of the above structural material was press-bonded to each of these materials, and dried. It well adhered to these materials, and a peel test resulted in fracture at the foam sheet portion of the structural material.
